Description
- This application claims priority to U.S. Provisional Application No. 63/408,202, filed Sep. 20, 2022, the contents of which are incorporated by reference herein in their entirety.
- The described invention relates to socks for use in a prosthetic assembly. Specifically, the described invention relates to prosthetic socks having a fabric disc applied to a distal end so as to reinforce and strengthen the distal end of the prosthetic sock or liner. Alternatively, the invention may apply to prosthetic liners as well.
- A residual limb normally experiences volume reductions over time which can have an outsized effect on the fit of an artificial prosthesis. Prosthetic socks are generally knitted pieces of fabric that serve to shore up the fit between a prosthetic liner and a prosthesis and can have varying thickness. These prosthetic socks generally need a channel for the receipt of the prosthesis and, due to their knitted nature, can have loose threads around that channel. These loose threads sometimes end up going into the lock when the patient engages the prosthesis causing the lock to become jammed. Previous attempts to solve this issue included gluing around the open channel in the sock but the glue would become hard and bulky upon drying thereby causing patient discomfort. This can also create distal thickness stacking which could create up to a quarter of an inch growth which can push the patient out of a socket which is uncomfortable.
- Therefore, it is an object of this invention to provide an improvement which overcomes the aforementioned inadequacies of the prior art devices and provides an improvement which is a significant contribution to the advancement of the prosthetic sock art.
- Another objective of the invention is to create a strengthened distal end of a prosthetic sock that allows for engagement with a prosthetic lock without jamming.
- Another objective of the invention is to not require the use of glue around the interior rim of the channel of the prosthetic sock.
- The foregoing has outlined some of the pertinent objects of the invention. These objects should be construed to be merely illustrative of some of the more prominent features and applications of the intended invention. Many other beneficial results can be attained by applying the disclosed invention in a different manner or modifying the invention within the scope of the disclosure. Accordingly, other objects and a fuller understanding of the invention may be had by referring to the summary of the invention and the detailed description of the preferred embodiment in addition to the scope of the invention defined by the claims taken in conjunction with the accompanying drawings.
- The present invention relates generally to a sock comprising an outer fabric layer that tapers from a proximal end down to a distal end. The distal end of the sock further comprises a fabric disc which can be mechanically or chemically applied to the outer fabric layer. The distal end of the sock further comprises a channel which allows for the receipt of a prosthetic (not illustrated). Likewise, the fabric disc comprises a complementary disc channel which allows for the receipt of a prosthetic. No glue is present on the interior rim of the channel or the interior disc rim of the disc channel. Preferably the fabric disc is made of polyester but may be made of any material that has a horizontal stretch that is at least 20% less than that of the exterior fabric layer. Further, the fabric disc preferably has an outer diameter between 0.5 and 4 inches and an inner diameter between 0.25 to 1 inches. The fabric disc is attached to the distal end using a heat activated polyurethane adhesive layer but may be applied using fabric glue as well.
- The foregoing has outlined rather broadly the more pertinent and important features of the present invention in order that the detailed description of the invention that follows may be better understood so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention.

FIGS. 1-2A illustrate a preferred embodiment of asock 100 comprising anouter fabric layer 110 that tapers from aproximal end 120 down to adistal end 130. Thedistal end 130 of thesock 100 further comprises afabric disc 140 which can be mechanically or chemically applied to theouter fabric layer 110. Thedistal end 130 of thesock 100 further comprises a centrally placedchannel 150 which allows for the receipt of a prosthetic (not illustrated). Likewise, thefabric disc 140 comprises acomplementary disc channel 160 which allows for the receipt of a prosthetic through the creation of acentral channel 400. No glue is present on theinterior rim 190 of thecentral channel 400 or theinterior disc rim 200 of thedisc channel 160. - Preferably the
fabric disc 140 is made of polyester but may be made of any material that has a horizontal stretch that is at least 20% less than that of theouter fabric layer 110. For example, if theouter fabric layer 110 stretches five inches at the proximal end, thefabric disc 140 should only be able to stretch four inches. In terms of shape, thefabric disc 140 anddisc channel 160 are preferably circular but may be any shape that allows for the receipt of a prosthesis, such as square or oval-shaped. When thefabric disc 140 is circular in shape, thefabric disc 140 preferably has anouter diameter 170 between 0.5 and 4 inches and aninner diameter 180 between 0.25 to 1 inches. Thisinner diameter 180 is the same for thecentral channel 400. Thefabric disc 140 is attached to thedistal end 130 using a heat activated polyurethane adhesive layer but may be applied using fabric glue as well. - Alternatively, as shown in
FIGS. 3-4A , the present invention may be used in combination with aprosthetic liner 300. Theprosthetic liner 300 may further comprise aninner elastomer layer 310 comprising either silicone, urethane, or a thermoplastic elastomer such as poly(styrene-ethylene-butylene-styrene), i.e. SEEPS, or any other linear triblock copolymers that are capable of making a solid gel composition.
